T 0 all whom it may concern.

Be it known that I, FRANK E. OILER, a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Cameras Provided with Automatic Fluid-Treating Mechanism, of which the following is a specification.

My invention relates to photographic cameras provided with mechanism for developing, fixing or otherwise manipulating or treating with fluids the sensitized material.

It is the object of my invention to provide a machine of this class adapted for the direct production of prints from a continuous roll of sensitized material such as common bromid paper, and having manually controlled means for severing the exposed sections or sheets ofmaterial from the roll and starting the fluid-treating operations, and automatic means for continuing the fluid-treating operations and carrying the print outside of the light-proof casing in which the operations are commenced.

Further and .more particular objects of myinvention relate to the specific structure and mode of operation of certain elements of the machine, and will be more particularly pointed out hereinafter.

Constructions embodying my invention are illustrated in the accompanying drawings, in which Figure 1 is a longitudinal vertical section of the machine, Fig. 2 is a side elevation thereof. Fig. 3 is a rear end elevation. Fig. 4 is a detail, drawn to an enlarged scale. of some of the mechanism shown in Fig. 1. Fig. 5 is a detail transverse section on the plane indicated by the line ma2 of Fig. 4, Fig. 6 is a detail horizontal sectional view taken above the carrier magazine. Fig. 7 is a detail transverse section showing the motor and disconnecting device, Fig. 8' is a detail side elevation of the same, Figs. 9, 10, 11 and 12 aredetails showing the various steps or phases of the operation of severing the sheets and causing them to be engaged by the carriers, Fig. 13 is a plan view of one of the carriers with the clips in released or spread position, Fig. 14 is a similar view with the clips in the positions assumed while they are in the magazine, Fig. 15 is a rear elevation of a carrier and the bridge-bar, Fig. 16 is a transverse section of a carrier and the bridge-bar, Fig. 1'7 is a transverse section through one of the carrier clips in closed position, Fig. 18 is a similar view showing the clip open, Fig. 19 is a detail side elevation of the device for moving the carriers through the end of the casing, Fig. 20 is a detail transverse section taken on the plane of the line ;1 y of Fig. 19, Fig. 21 is a detail horizontal section through the lighte-vcluding slide of the carrier-actuating or conveyer frame, Fig. 22 is a detail of one of the crank stop-latches, Fig. 23 is a detail vertical section on the plane of the line zz 'of Fig. 0, showing in elevation a portion of the operating mechanism, and Fig. 24 is a detail horizontal section above the crossplate which supports the carrier feed-slide.

In carrying out my invention 1 provide a suitable casing 1, to which at the upper part of the front end thereof is attached a camera bellows 2 connecting with a suitable lens, not shown in the drawings. A bed-plate 3 is extended outfrom the front of the casing to support the lens in the usual way. In the lower part of the casing at the front thereof is formed a storage chamber 4 in which is disposed a roll X of the sensitized mate ial used with the machine. Access to the storage chamber is afforded by means of the door 5 in the front of the casing.

The strip of material from the roll X is passed up through an opening at the top'of the chamber 4, around the semi-cylindrical guide-bar 6. below the flap 7 and along the bottom of the exposure chamber 8 to the feed rolls 9. The upper part of the exposure chamber is formed by a mirror 10 which receives the light rays projected through the bellows 2 by the lens, and reflects the same down onto the strip of sensitized material, at the sametime rectifying the image of the object photographed so that the same will not appear reversed as it would if the image were received directly from the lens. The upper edge of the mirror adjoins an opening in the casing through which the mirror may MACHINE be" withdrawn therefrom, and said opening is normally closed by a slide 11 which may be opened slightly to permit the bottom of the exposure chamber to be viewed in focusing.

The feed rolls 9 are journaled at their ends in the side-frames 12, and at one end are provided with pinions 13 which mesh with each other, and one of which meshes.

with a gear 14 arranged-as shown in Fig. 5. The said gearis connected with a crank 135 at the side of the casing, and is preferably angle-bars 15 which are connected to each other at their rearward ends by the crossbar 16, and on which is arranged the deck 17 which supports the fluid tanks. The side frames 12 are connected to the bars 15 near the front ends thereof, and said side frames are connected with each other at their lower portions by the cross-bars 18. The side-bars "19 extend rearwardly from the frames 12 adjoining the upper edges of the fluid tanks, and said side-bars are connected with each other near their rearward ends by a crossrod 20, their rearward ends being supported by "the bars 19 which extend down to the bars '15. The upper portions of the sideframes 12'are connected with each other by means of across-rod 21, and the intermediate portion's of the side-frames are connected by the cross-plate 22, the bridge-bar 23, ledger-bar 24 and crossbar-28.

' a In the'side-frames 12 adj acent to the feedrolls are formed vertical guideways in which the ends of the upper and lower clamp-bars Q25 and 26 'are slidably held. The lower clamp-bar26 has rods. 27 extending down through the'cross-bar 28, and around said rods are disposed the coil springs 29 which normally hold the bar 26 in the raised posi- "tion shown in Figs. 1, 4, 5, 9 and 12. Be- 'low the cross-bar 28 the rods are providedwit'lrnuts which normally bear against. the resilient buffers '30, as shown, and limit the upward movement of the clamp-bar. The' upper clamp-bar 25 is connected by means of the rods 31'with the ends of the cam-levers 32 which. are fulcrun'iedon the shaft 33. Each ofsaid cam-levers 32 has two arms, one of which extends upwardly in frontof the cam-shaft 34, and the 'otherextends rearwardly below said shaft.' The rearwardly bar 37 and projects sufliciently below the same to enable it to extend downpast the foot of the upper clamp-bar. bar are connected the cam-rods 39 which at their upper ends are slotted andpass around the cam-shaft 34 adjoining the cams 40. Rollers 41 are carried on the sides ofthe rods 39 and engage the cams 40 by which the knife-bar is both raised and lowered.

The normal position of the knife-bar and clamp-bars is shown in Figs. 1 and 4, the adjacent edges of the clamp-bars being separated so as to leave anopening between them behind the feed rolls 9. After a section of the sensitized material has been exposed in the chamber 8, the crank 135 is turned to feed the strip of material out between the clamp-bars and over the top edge of the ledger-bar 24. The front edge of the strip of material engages the guide fingers 42, which are carried on the rearward side of the upper clamp-bar and which direct the strip downward. After the strip of material has been fed out between the clampbars, the camshaft 34 is turned by means of the crank 43 which is carried on the end thereof at the side of the casing, as shown. At the beginning of the movement of the cam-shaft the upper clamp-bar is moved downward into engagement with the strip of material so as to press the same against the lower clamp-bar as shown in Fig. 9. To

assist in holding the sheet of material the upper clamp-bar is provided at its lower edge with several pointed studs 44 whichperforate the strip and pass into corresponding openings 44 in the lower clamp-bar. After the strip of material has been clamped between the bars the knife-bar is moved downwardly so that thecutter-blade passes To the knife-- into the narrow opening between the'lower clamp-bar and the ledger-bar 24 and severs the clamped sheet. from thestrip of the material held by the feed rolls. The upper clamp-bar is then moved on downward,"

pushing the lower bar before it, until the rearward edge of the severed sheet Z is near the upper edge of the bridge-bar 23, at which position the carriers are engaged with the sheets, as shown in Fig. 10.

Each of the carriers comprises a frame formed by the rods 45 and 46 which pass through and are secured in the blocks 47,

masses and two clips mounted on the said frame near the ends thereof. The clips each consist of a lower jaw member 48 which is out toward the ends of the carrier and in engagement with the stops formed by the heads of the screws 55in the ends of the rod 46. In the rod 46 between the blocks a7 and the ends of the rod are formed notches 56, and the rearward sides of the pivot-lugs 57 of the upper jaws are extended so as to enter the said notches when the jaws are open, as shown in Fig. 18. The hooks 52 are employed as shown in said figure to hold the jaws of the clips open, and when the jaws are open the clips arehe-ld in the relative positions shown in Fig. ltby the engagement of the lugs 57 in the notches 56. The clips are secured in the positions shown in Figs. 14 and 1S preparatory to placing the carriers in the magazine. \Vhen the hooks 52 are released from engagement With the jaws 49, the springs 51 close the jaws and the lugs 57 are thus withdrawn from the notches 56 so that the springs 54 are permitted to push the clips out to the ends of-the rod %6, as shown in Fig. 13.

The magazine for the carriers has a cage or open frame consisting of the end members 58, the upper and lower transverse connecting members 59 and 60, and the vertical guide members 61. The lower connecting members 60 fit into channels and are thus slidably held in the frame cross-bars 18. At the side of the casing l is a door .62 which may be opened and the magazine drawn out through the same, as shown in Figs. 2 and 6, for convenience in placing the carriers therein. At each end of the magazine and near the'upper and lower ends of the members 58 are small sprockets 63 around which are passed the endless chains 64. To the vertically extending portions of said chains at the rearward side of the magazine are connected the ends of thecarrier followerbar 65, the ends of which extend through vertical slots in the members 58, as shown. At the front side of the magazine the ends of the counterweight follower-bar 66 are connected with the chains 64. The followerbars are so arranged upon the chains that when the magazine is filled with the carriers and the bar 65 is near the bottom of the magazine, the counterweight follower 66 will be near the top of the magazine and will support all of the counterweights 6T.

- weights.

The weights are so proportioned that they will more than balance the weight of .the carriers and willtlius tendto eject them from the top ofthe magazine. As the carriers are removed from the magazine and the counterweight follower descends, the weights 6? are successively engaged and supported by the pins 68 which are arranged as shown in Fig. at, being of graduated length" and the shorter ones thereof pass ing through slots made in the sides of the weight of the carriers in the magazine, and excessive upward pressure thereon avoided. The lowersprockets 63 around which the chains 64: are passed are connected with each other by a shaft 69 which is journaled in the end member-s58. Near the sprocket on the end of the magazine adjoining the door 62 in the casing is a pawl 70 which may be engaged with the sprocket to prevent rotation thereof and thus to retain the carrier follower atan i desired hei 'ht in the ma azine.

-47 thereof forma continuous column therein, the follower being pushed gradually downtoward the bottom of the magazine and being retained at its successive positions by the engagement of the pawl 70 with the sprocket. After the magazine has been filled with the. carriers it is pushed back into position within the casing, the pawl 70 disengaged from the sprocket so that the counterweights are permitted to pull the column of carriers up against the lower side of the crossplate 22, and the door 62 closed.

On the lower side of the cross-plate is arranged the carrier feed-slide 71 which is connected with the cross-plate by means of the guide-blocks 72 which extend up through slots in the plate and have flanges extending I over the upper side thereof. The end portions of the feed-slide carry round studs 73 which extend outthrough the side-frames 1:2 and are engaged by the forked ends of the cam-levers 74: which are secured upon the ends of the shaft 33. said c anrlevers H carry rollers which engage the cams 75 by which the levers are actuated to move the feed-slide rearwardly, and upon the shaft-33 inside of the frames are secured cranks 76 which carry rollers engaging the cams 77 by which the feedslide is moved forwardly. The feed-slide carries fingers 78 which are alined transversely with the blocks 47 of the carriers in the magazine. During the rearward move- The upper arms of The counterweight load is tl usi kept in approximate proportion to the ment of the feed-slide the ends of said gers 78 engage the blocks 47 of the uppermost carrier and push the same from the magazine rearwardly over the bridge-bar 23. As the clips on the carriers pass from under the plate 22 the hooks 52 are engaged by the clips 79 at the edge ofsaid' plate and are turned back so that the jaws of the clips are permitted to close. Before the jaws are released, however, the rearward ends or nose portions thereof enter the notches 80 i in the clamp-bars and pass above and below the edge of the sheet ofmaterial held thereby, so that as the jaws close they engage and .grip thesheet, as shown in Fig. 10. In the upper side of the bridge-bar are channels 81 through which the lower portions of the upper ends of: the levers are provided with pins adapted to be engaged by the inclined faces of the blocks 86 which are disposed on the rearward side of the upper-clamp-bar near its ends. As the upper clamp-bar approaches its uppermost positioi the said inclined faces of the blocks 86 turn he levers so that the lower ends thereof are disengaged from the pins 85 and'the lower clamp- .bar is thus released so that the springs 29 are permitted to move it up to its initial position, as. shown in Fig. 12. Before the clamp-bar is released the forward movement.

of the fe'edslide is commenced so that the fingers 78 are out of the way of the bar when its upward movement is commenced. At

are released so that the. edge of the sheet of material islheld under tension and the'same caused to hang from the carrier in a vertical plane. -By the movement of the clips away from each other anyexpansion of the sheet due to its immersion in the treating,

fluids is also compensated.

After the carrier is engaged with the sheet of material held by the clamp-bars, the up per-clamp-baris moved upwardly to a position such as shown in Fig. 11, after which the carrier feed-slide is moved rearwardly to the position shown in said figure and the carrier thus pushed through the space between the clamp-bars so that the end portions of the rod l5 engage the inclined end portions of the side-bars 19 and slide down the same to the first of-the notches in the up 'per edges of the side-bars.

vent the carrierfrom catching on the lower In order to pre-' clamp-bar in passing over the same, the

bridge-bar 23 is provided on its upper fsurface with inclined portions 82- which are engaged by the blocks 47 and the carrier thus raised over. the lower clamp-bar. During the upward movement of the upper clamp-bar the lower clamp-bar is retained at its lower position shown in Figs. 10 and 11, by means of the curved levers 83 which are fulcrumed on: the side-frames -12 as shown in Fig. 5, and of which the lower. ends are normally turn'edinwardly by means of the springs 84. The said lower ends of the levers engage the clamp-bar when said ins 85 on the lower lower position, and thus retain the same in said position until. they are released. The

ar is pushed to itsthe conclusion of the forward movement of the feed-slide the carriers in the magazine are permitted 'to moveup until the upper most carrier engages the cross-plate 22 and said carrierzis in pos'ition to be engaged and pushed out ,of the magazine "by the next rearward movement of the feed-slide.

. As the sheet of sensitized material is fed out by the feed rolls and the rearward edge thereof directed. downward 'by the guide fingers 42, the said edge of the sheet enters the front portionof thefirst fluid-tank A. In said tank Anear the front side thereof is disposed a partition-plate 87 which .eX-

near the bottom thereof, and which serves to prevent the. sheet of material, whileit is relatively stiff and before it is moistened by the fluid in the tank, from being pushed back in the tank far enough .to engage that sheet of material which hangs in theta'nk at the next succeeding position.

At the positions indicated .on the side .bars19 sprockets 88 are revolubly mounted,

and, endless chains 89 passover said sprockets and extend down and around the sprockets 90 which are'carried on the ends of the shafts 91-and 92. Said shafts are journaled in suitable bearings arranged .on the anglebars 15, and on their central portions carry sprockets which are connected with each other by ai'chain 93. so that when the shaft 91 is driven the shaft 92 is actuated at the same speed. The shaft 91' carries asprocket which is connected by the chain 94 with the driving sprocket 9'5. The1conveyerframes 96 are connected with the chains 89- at similar positions thereon so that when said chains are driven all parts of the conveyer tends from the top of the tank to. a point frames'move in paths'the :same as thoseof the chains. At the upper .edges of the conveyer frames are. the guide-plates 97 which are 'so arranged as to extend up "past/the ends of the rods 45 of-the carriers'and prevent transverse displacement of the carriers. Along the lower and: inner edges, of the guide plates 97 arebars 98036 which the upper edges have V-shaped notches made therein at equal intervals the same as those between the notches in the upper edges of the side-bars 19. The diameters of the I sprockets 88 and 90 are such that the longitudinal movements of the conveyer frames are the same as the distances between the said notches in the bars 98 and the side-bars 19. The vertical movements of the conveyer frames are such that during the forward longitudinal movement the bars 98 will swing below the notches in the side-bars 19 and thus deposit the ends of the rods 15 of the carriers in said notches, and at the beginning of each upward movement each carrier will be engaged and lifted by the conveyer frames, and at the downward movement thereof deposited in the next rearward set of notches in the side-bars. As thecarriers are thus intermittently moved rearwardly the sheets. Z of the sensitized material carried thereby are successively immersed in the fluids contained in the tanks A, B, C, D, E and F. The relative duration of treatment by any of the liquids contained in the tanks is determined by the number of times each sheet is dipped in the fluid. The actual time of each immersionof the sheets is determined by the driving mechanism of the'conveyer frames, and said driving mechanism may be adjusted to vary the period of immersion, as follows: The shaft of the driving motor 99 carries a worm 100 which meshes with a worm-wheel 101 car ried on a shaft 102. The said shaft is journaled in bearings 103 and the driving sprocket 95 is revolubly mounted on the shaft. Adjacent to the driving-sprocket the clutch-sleeve 10 1 is mounted on the shaft and slidably connected therewith by a spline 105. On the end of the sleeve adjoiningthe sprocket is a pin 106 adapted to engage a similar pin on the side of the sprocket and thus drive the same. A spring107 is arranged on the shaft between the sprocket and sleeve and tends to push the sleeve away from the sprocket and thus disengage the same therefrom. The-outside of the sleeve is threaded, as shown, the thread being preferably of the buttress type and having the radial faces of the thread opposite the end of the sleeve adjoining the sprocket. A rocking-shaft 108 carries atone end an arm 109 which is adapted to engage the threaded surface of the clutch sleeve, being normally pressed toward the sleeve by means of a spring 110 placed under an arm 111 carried 102 continues to rotate and the arm 109 is in position to engage the sleeve. As the conveyer frames reach the lower limit of their movement one of said frames engages the upper end of a rod 112 which is held in a suitable guide as shown in Fig. 7 and which is normally held up by a spring 113. To the lower end of the rod 112 is articulated the push-rod 111 of which the lower end engages the arm 111 so that when the rod is pushed downwardly by the movement of the conveyer-frame the rocking-shaft 108 is turned and the arm 109 disengaged from the clutch-sleeve. lVhen the arm is disengaged from the sleeve the spring 107 moves the sleeve longitudinally away from the sprocket 95 and thus disengages the same therefrom so that the sprocket is nolonger driven thereby. As the clutch-sleeve moves toward the outer one of the bearings 103 the end thereof engages the collar 115 which is adjustably secured on the trip-rod 116. The said trip-rod is slidably held in the bearing 103, the outer end thereof is connected with the push-rod 111, and it is normally pushed inwardly by a spring 117 which extends into a-recess in the bearing and which engages astop-collar 118 secured on the rod. \Vhen the collar 115 is engaged by the clutch-sleeve and pushed outwardly the push-rod is moved laterally as shown by the dotted lines in F ig. 7 so that the end thereof is disengaged from the arm 111 and the rockingshaft thus permitted to turn-and rengage the arm 109 with the clutch-sleeve. \Vhen such engagement is made the sleeve begins its return movement toward the drivingsprocket and, after a predetermined number of turns of the driving-shaft, again engages and begins to actuate the sprocket 95. Thus after each downward movement of the conveyer frames to deposit the sheets of material in the fluid tanks, the movement of the frames is discontinued for a time and the sheets allowedto remain immersed in fluids. The duration of the immersion may be regulated by varying the position of the collar 115 on the trip-rod 116, thus varying the distance which the clutch-sleeve moves away from the driving-sprocket, and consequently the number of turns of the driving-shaft which is required to return the clutch-sleeve to engagement with the sprocket. It is, of course, assumed that the-motor runs continuously and at a unifornrspeed.

The upper and rearward portion of the casing 1, covering the space into which the carriers are lifted by the conveyer frames, is made removable in order to provide access to the fluid tanks and operating mechanism. The joint around the edge of the removable portion is rendered light-proof by any suitable means, such as the lap-strip 119 shown. All of the fluid-treating operations required to be conducted in darkness are made within v the tank' F each of the side-bars 19 has a the tanksA, B, 0, 1), and E, so that when the prints are immersed in the fluid contained in the tank F they are ready to be exposed to'light. 'The tank F is so arranged that half of the same extends outside of the casing, and to the lower edge of the casing above the tankis attached *a flap 120 of flexible opaque material, which normally dips-into the fluid in the tank, When the machine is exposed to bright light coming "from a sourcesuch that the rays may enter the exposed surface-of the fluid in-the tank F, it maybe necessary to employ an opaque or colored fluid in said tank in order to prevent the light entering the cas'ing by refraction and reflection in the fluid; Adjacent to long notch formed in the upper edge thereof, as shown, the extent of the notch being 'such that one end is insidetand the other outside of the casing. After a carrier is lifted by the. conveyer frames out of the rearward part of the tank 'E,-at the next downward movement it is depositedso that the print carried thereby hangs in the front part of the'tank F- and the ends of the rod 45 of the carrier rest in the front part of said long notches in theside-bars. During the forward movement of the .conveyer' frames, and while all of the prints are immersed in the tanks, the carrier holding the print in the tank F is moved from the inside to the outside of the casing by the following means: In each of; the side-bars 19 adjoining the ends of the tank F are recesses in which are rotatably mounted the pinions 121. Rack-bars 122 and123 are slidably dis posed in grooves-made in the sidebars and intersecting the pinion recesses, the teeth of the rack-bars meshing, respectively, with the upper and lower portions of the pinions. The rack-bars are retained in the grooves-by means of the plates '124arranged and secured to the side-bars as shown invFig. 19. At the rearward ends-of the bars 122 are formed the lips 125 which extend up infront of the rod 45 of the carrier, Onthe front ends of the bars 123 are laterally projecting pins 126 adapted to be engaged bythe fi'ngers 127 and 128 carried by the conveyer frames. The forward movement of the con veyer-frames,' being communicated to the rack-bars 123 by the'fingers 127 rotates the pinions and moves the rack-barsI122 rearwardly. During said-movement the rod 45 of the carrier is engagedby the. lips 125 andthe carrier. thereby pushed I outside the {easing, [passing 7 under -therflap 120 which; re-' turns to its normal position; when the :car; rier, is', past the same. After the upward movement of the conveve'rframes and du'r- 7 ing therearward movement thereof the rack bars are'returned to their-normal; posif tions by the engagement of the} fin er's "128* with the Pins "126 .on the lo'werrackar's, as

indicated in Fig. '19. After a carrier is veyer frames are connected with the main orinner frames 96 by the bars 130 which pass through vertically extending slots in the casing,-from which the light is excluded by .the means shown in detail in Fig. 21-. The

bars 130 pass slidably through openings in the vertical slide-bars 131, and the latter bars are held inguideways 132 secured upon the casing adjoining the vertical slots in the casing. The vertical movementsof the con-- veyer frames are permitted by sliding of the bars 131 in the guideways, and the longitudinal movements of the frames are permitted by the movement of the bars 130* thecasing areprovided one or more tanks, 1

through the vertical slide-bars. Outside of G and H, into which the prints are. conveyed from the tank F, be removed by l1and.-

, On the side of the casing adjacentto the cranks 43 and 135 are pivotally mounted the stop-latches 133-. Said stop-latches have hook-like notches therein adapted to engage pins arranged on the cranks as indicated by the dotted lines in Fig. 2. Springs 134 arranged as indicated inFig. 22, normally turn the latches toward the "cranks. When one of the cranks is tobe turned, the handle thereof is grasped and the'stop-latch turnedwith the thumb until the latch is disengaged from thecrank. The crank then turned one complete revolution, at the conclusion ofwhich it again engages the latch and is stopped thereby' 'From the foregoing the. operation of the machine will be-apparent'. It will be-noted and from which they may that the only manual operations required in the production of prints by the machine are the making of the proper exposure by openung and closing the lens' shutter of the camera, the turning of the cranks 43' and 135, and the removal of the prints from the tank H. The'treating of the sheetsof sensitized material withthe fluids, being auto .matically performed, may be regulated with.

exactness and the machine thus employed with processes requiring greatnicetyin the- Assa i'elamanipulation of the material.

tively large number of prints are under. treatnient atth'e same time, the machine. has f af large capacity even with processes requiring considerable time in the. treatment of each print. As the fluids'which areiused do not come-into contact with any of 'the,mecha"- nism, and touch nothing but the tanks and the prints, corrosive substanceslmay be used in the treating 'of the prints without neces- Sita'ting any part of the machineother than the tanks to be. madeof material s capable of resisting the corrosiveaction of the fluids.

This enables the use of the machine in processes which could not be employed with machines using flexible belts and the like to carry the prints through the fluids, since the belts would be destroyed by the corrosive fluids used in such processes.
